Application filed February 8, 1911. Serial No. 607,289.

T0 all whom it may concern Be it known thin; 1, Amunon W. :tiown, ofPhilndelphin, in the county of Ilhiladelphiu and Eltute of Pennnylrnnin,have invented certain new and useful inipriwennrme in tires; tormitoinohilcs, reliiohm, or the like, and more eepeehitly tojnon-inltzited or until ioned tires used for this purpose, Whercot tirestnrueture wherein the loud preusure and ried enhirol y by n trusslocated within the, tire and rat) disposed relative to the parts of thetire that the strain or pressure on the trend is conveyml in n rndiuldirection through said truss to at supporting rim uud centralizedrelative to the rim.

A further ohjoet of the invention is 'to provide it tire oi. the :ihoreohnrzn'trr with n hollow ehninher located between the truss and thetread, wherehy the pnrts znljznrnt the trend min spread to ntlord uhotter Contact with the surface on which ihe trend ski dd in 1 These andotl'uu: ohjtets will in purl he in pnrt he lurreinnl'ter more fully ile1e1-il wl.

It will,therefore, he neon thnt by my improved structure, the truss re: ceiresall the 10nd pressure, that said pl'er-I- sure is centralized dirertlyover the rim and to n great extent 1 have provided a sell containedtire, that is a tire wherein the strain-i to Whieh it is subjected nreconveyed to the centr: 1 portion of the rim, thus :ivoiding, to atgreat, extent. the lute 'ul strnine on the tire und lnternl stirnins onthe supporting rim.

The tire as herein shown is sumgortcd by a rim 12, which may be made ofsheet steel or cast or in any desired wuy. Said rim is formed withflanges 17. 17, which project outwardly and pre'fe ably to 2 pointabovetio lifi

'1 0 ill i the chamber 7, in the tire. The outer side ing curvedtransversely edges of the rim are curved as at 18, to form astrengthening rib. In order to prevent the tire from creeping in therim, 1 have provided indentations 19, which are spaced throughout therim, and said indentations are embedded in the tire so as to hold thesame from creeping on the tire. The rim may be made in two parts ifdesired, and bolted together in a suitable way, and any desired. wellknown means may be used for securing the rim to the telly 2, of thewheel. The chamber 6, in the tire structure will allow the partsadjacent the tread to spread under pressure and this spreading of theseparts will through the structure in the tread cause a gripping of thetread on the surface on which said tread rolls, which will to a certainextent prevent skidding, The central projection in the outer wall of thechamber 7, which engages the central rib of the truss, will prevent anylateral slipping of said rib of the truss on said outer wall of thechamber and thereby aid in centralizing the pressure on the tire whichis conveyed. by the truss to the supporting rim and folly. It isobvious'that minor changes in the details of construction and thearrangement of the parts may be made without departing from the spiritof my invention, as set forth in the appended claims.

Having thus described claim:

1. A tire comprising a rubber body portion having a chamber formedtherein; a truss located in said chamber, said truss beand having itsouter edges rounded; a central rib projecting out wardly from said trussmember, the wall in said chamber having an inwardly projecting ribengaging the rib on said truss whereby the load pressure on the truss isconveyed my invention, ll

i'vardly from said truss member, the wall of said chamber having aninwardly projecting rib engaging the rib on said truss whereby the loadpressure-on the truss is conveyed through said central rib and the outerportions of said truss to the central portion of the supporting rim; anda second chamber located centrally of the tire and between said firstnamed chamber and the tread of the tire.

3. The combination of a rim havingoutwardly projecting flanges; a tirelocated between said fianges; means for preventing the tire fromcreeping on the rim, said tire comprising a solid rubber portion. havinga chamber formed therein; a truss located within said chamber, saidtruss being curved transversely and having the outer curved surfacethereof engaging the inner wall. of said chamber, the outer edges ofsaid truss engaging the outer wall of said chamber and engaging said ribon the truss, said the hav ing a second chamber formed therein betweenthe first chamber and the tread of the tire, said second chamber formingcolumns in said tire which are located between the central rib and theouter edges of the truss.

In testimony whereof, I have hereunto.

signed my name at Philadelphia, Pennsylv Vania, this sixth day ofFebruary, 1911.
